STREET-CLEANING DEVICE.

Specification of Letters Patent. Patented 19, 1921. 7

Application filed January 4, 1921. Serial No. 434,985.

.T 0 all whom it may concern.

Be it known that I, FRANK M. GRADY, a citizen of the United States, and resident of Butte, in the county of Silver Bow and State of Montana, have invented a new and Improved'Street-Cleaning Device, of which the following is a full, clear, and exact description.

My invention relates to a street cleaning device, and aims to provide certain new and useful improvements in devices of this character.

In connection with street cleaning implements, such as snow scrapers, etc., it is a well appreciated fact that it has been customary to manipulate the same at such an angle to the direction of travel that the street will not alone be cleared in the path in whichthe device moves, but the snow or other substances will be moved to one side thereof.

These devices have either been moved by the operator in such a manner that they are arranged at an angle to a plane transverse to the direction of travel, or else the blade, scoop, or brush has been mounted at a fixed angle with respect to the handle.

My invention aims to provide improvements in connection with the latter class of device, which presents defects, in that it is necessary to always move in the same direction to effect a deliverance of the material cleared from the side walk or street, by the device, from one side of the device. Thus, assuming that a strip of sidewalk is to be cleared of snow, it is necessary for the operator to manipulate devices of this character in a straight line adjacent the buildings. Subsequent to this, it is necessary for the operator to return to the starting point, to effect a further clearance and sidewise movement of the material being cleared toward the curb.

With this in mind I have constructed a snow remov r or scoop, which is not necessarily limited to this adaptation, and by means of which it will be possible to have the cleaning implement arranged at an angle to the handle without the necessity of returning to the original starting point each time, as the material to be cleared is displaced toward the curb.

A further object of my invention is the provision of a device of this character which shall be extremely simple in construction.

Further objects of invention will appear in the annexed specification and draw ings which latter present one practical embodiment of my invention, and in which Figure 1 is a plan view of a cleaning de- VICG CODStIUCtSd in accordance with my invention.

Fig. 2 is aside view thereof.

Fig. 3 is an enlarged sectional view taken along the lines 3-3 of Fig. 2, and

F f is a somewhat diagrammatic view showing the utility of the device in use. Referring now more particularly to Fig. 1 it will be seen that the reference numeral 5 indicates, in the embodiment illustrated, a

scoop. which may be of any desired construction, and which is conveniently provided with any suitable means such as straps, 6, permitting of its association with a handle.

Contrary to the conventional construction, my device includes a pair of handles 7 the inner ends of which are hingedly secured to the strap 6, as has been indicated by the reference numeral 8.

Also hand portions 9 may be conveniently associated with the outer ends of the handle, to permit of the ready gripping of the same,

and a link 10 has its ends plvotally secured one to each of the handles 7.

Thus it will be seen that I have provided a cleaning device in which the angle of the scoop or other implement affixed to the handle may be varied with respect to the handle by a simple manipulation of the parts.

With regard to the utility of a device of this nature. it will be noted, reference being had to Fig. 4, that assuming thatflk is the surface to be cleaned, B the innermost edge of this surface, and Cthe line to which the snow or-other debris is to be moved, that the implement, is primarily manipulated along the line B over the surface A and the material will be cleaned from this surface and moved toward the center portion of the surface A. A subsequent moyernent in areturn direction on the part of the cleaning device will result in the substance being cleaned, being removed from the center of the surface A to the line C.- e

Thus I have provided a cleaning device which may be manipulated to advantage to permit of the expeditious removal of snow or other substances, and it will be understood that numerous modifications of structure might readily be resorted to without in the least departing fromthe spirit of my invention, which I claimfas; I

1. A cleaning device, including a cleaning element, and a pair of handles, whereby the device is pushed, each handle having one of its ends hingedly secured to said cleaning element. l a

2. A cleaning device, including a cleaning element, a, pair of handles each having one of its ends hingedly secured to said cleaning element, and a link extending between said handles, andhaving its ends pivotally secured one to each of the same.

'3. A cleaning device, including a scoop, handles hingedly secured to said scoop, and a link extending between said handles and having its ends pivotally secured one to each of the same. i i I V FRANK M. GRADY; 1
